MOTOR-CYCLE.-

SPECIFICATION forming part of Letters Patent No. 731,207, dated June 16,1903. Application filed January 29, 1903. Serial No. 140,972. (N dL) To(0% whom it may concern:

Be it known that we, STEPHAN NECHLEDIEL,

residing at Newark, and JOHN PAWLITsCHEK, residing at Orange, in thecounty of Essex in Motor-Cycles; and we do hereby declare the followingto be a full, clear, and exact descrip tion of the invent-ion, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which form a part of thisspecification.

The present invention has reference generally to improvements inmotor-cycles; and the invention relates more particularly to a novelarrangement of motor upon the frame of a bicycle and a novel means ofattachment of the motor upon the frame of the vehicle.

This invention has forits principal objects to provide simple means ofattachment of the motor to the frame of the vehicle with a view oflocating the heavy motor upon the rear end portion of the; vehicle-frameback of the seat, whereby the weight of the motor is distributed at apoint above the center of the rear wheel, and the vehicle thereby ismore perfectly balanced.

The final results are that there is less danger of weakening the frameof the vehicle and the danger of accident is reduced to a minimum, and,furthermore, the vehicle is more easily propelled by the rider whenusing the pedals, and when striking a stone or other obstruction in theroad there is less danger of upsetting the vehicle and throwing therider.

With the various objects of the present invention in view our inventionconsists in the general arrangements of devices and combinations ofparts, as well as in the details of construction of the means forattaching the motor to the frame of the bicycle, all of which will befully set forth in the following specification, and then finallyembodied in the clauses of the claim, which form a part of and areappended to the said specification.

The invention is clearly illustrated in the accompanying drawings, in-which I Figure 1 is a side view of the rear portion of the frame of abicycle, a single-cylindered motor, and a novel means of attaching thesaid motor in position. Fig. 2 is a top or plan said motor in position,the said view being made on an enlarged scale and the relativepositionof the motor with said frame being indicated in dotted outline.Fig. 3 is a longitudinal vertical section of said frame, said sectionbeing taken on line 3 3 in said Fig. 2; Fig. 4 is a side elevation of abicycle provided with a double-cylindered motor and a modifiedconstruction of attaching frame or means for locating said motor at apoint above the rear wheel of the bicycle and back of the seat orsaddle.v Fig.5 is a rear view of the bicycle-frame, said motor, and saidmotor-attaching frame; and Fig. 6 is a plan view of said motor-attachingframe, a portion of said frame being represented in horizontal section.v 7

Similar characters of reference are employed in all of saidhereinabove-described views to indicate corresponding parts.

Referring now to the said drawings, the reference character 1 indicatesthe frame of the bicycle; 2, the saddle-post of said frame; 3, the rearfork, and at the rear axle of the vehicle. Suitably secured upon theopposite end portion of the rear-axle 4 are a pair of upwardly-extendingposts 5, which are secured at their upper ends to a laterally-extendingbar 6, as clearly illustrated in Figs. 2 and 6. This bar 6-is usually atube in which is a bolt or rod 7, having its opposite end portionsprovided withscrew-threads for the reception and arrangement thereon ofnuts 8.

The motor attaching or supporting frame employed with asingle-cylindered motor, as represented in Figs. 1, 2, and 3, consists,es-

vided with downwardly-curved parts 10 and having their perforated endportions 11 arranged upon the projecting ends of the bolt or rod 7 andsecured in position against the ends of the bar 6 by means of the nuts8, as illustrated. The curved parts 10-of said bars or arms 9 are madewith forwardly-extending members 12, which are connected by means of amember 13, having a pair of grooves to sentially, of a pair of side barsor arms 9, pro- View of the frame or means for attaching enable thefitting of said member 13 upon the rear halves of the members of thefork 3. The said member is provided with a'screw-threaded hole 14, intowhich is secured the end ofa' bolt 15, said bolt being passed throughahole 17 in a suitably-grooved clamping-plate 16 upon the oppositehalves of the members of the fork 3, when the bolt is screwed tight bymeans of its head 18. The said member 13 is also provided with arearwardly-extending lug or projection 19, having a screw-hole 20.Located upon the opposite sides of the members of the fork 3, at asuitable point above the member 13 and plate 16, are two othersuitably-grooved clamping-plates 21 and 22, the said plates beingclamped in place by means of a bolt 25, which is passed through a hole24 in the plate 22 and has its screw end screwed in a screw-threadedhole 23 in the plate 21 when turned by means of its head 26. The saidplate 21 is also provided with a rearwardly-extending lug or projection27, which is provided with a hole 28 for the reception of a bolt 29,having its lower end screwed in the screw-hole of the lug 19 and tightlyheld by its head 30, thereby connecting the upper clamping means withthe lower clamping means of the motor-attachin g frame and providing asafe and strong means for attaching said frame to the fork 3 of thebicycle. Another purpose of the two clamping-plates 21 and 22 and thebolt 29 is to serve as a means for taking up the slack in thedriving-chain 88 from the motor to the sprocketwheel 39, which isreadily accomplished by loosening the bolt 15 and turning the bolt 29 inthe proper direction and when the proper adjustment is made then againtightening the bolt 15, whereby the parts are once more retained intheir fixed positions.

The single-cylindered motor for driving the bicycle is indicated by thereference character 31, and 32 is the lower casing of the same.

As will be seen from an inspection of Fig. 1, the curved parts 10 of therespective side bars 9 conform to the lower circular marginal edge ofthe said casing 32 and are secured against the opposite sides of saidcasing in any suitable manner,and preferably by means of bolts 33, asshown.

When the motor is a double-cylindered one, as indicated in Figs. 4: and5, then the motor attachment or supporting frame comprises a pair offlat and closely-located supportingbars 34, which are secured upon theupper fiat surface 36 of the casing and between the two cylinders 37 bymeans of the bolts 38, as indicated more especially in Fig. 6 of thedrawings. In all other respects the general construction of this form ofmotor attaching and supporting frameis similar to that hereinabovedescribed and need not, therefore, be further described in detail.

The novelty and general utility of our present invention will be clearlyevident from the hereinabove description of the same, the

. main features of the same being the location of a motor for drivingthe bicycle directly above the rear axle and wheel of the vehicle backof the seat, or saddle and the novel means of attachment of the motor tothe frame of the vehicle, all for the purposes hereinabove set forth.

We are aware that changes may be made in the general arrangements of thedevices and in the combinations of the parts without departing from thescope of the present invention. Hence we do not limit our invention tothe exact arrangements of the devices and combinations of parts asdescribed in the previous specification and as illustrated in theaccompanying drawings, nor do we confine ourselves to the exact detailsof the construction thereof of the said parts.
